BRIQUET-MACHINE.

Specification of Letters Patent. Patented June 10, 1919.

Application filed October 10,1918. Serial No. 257,606.

T 0 all whom it may concern:

Be it known that I, SWAN E. lYIOREN, a citizen of the United States, reslding at Biwabik, in the county of St. Louis and- State of Minnesota, have invented certain new and useful Improvements in Briquet- Machines, of which the following is a specification. g

This invention seeks to provide a machine which may be built at a low cost and operated economically and efliciently to produce briquets of peat or other material. The inventionseeks to provide a machine for the stated purpose in which the briquets will be firmly compressed and provision made for preventing breakage to the operating parts in the event that large rocks or other non-compressible foreign matters should be contained in the material being treated, and a further object of the invention is to provide eflicient means for effecting discharge of the formed briquet. Other incidental objects of the invention will appear inv the course of the following description and it is to be understood that the details of construction shown in the accompanying drawings are illustrative only and that various changes maybe made therein Without involving any departure from the spirit or scope of the invention as the same is defined in the claims following thedetailed description. M

In the accompanying drawingsi Figure l is a side elevation with parts broken away and'parts in section of a machine embodying my invention;

Fig. 2 is a plan view ofthe same; Fig. 3 is a longitudinalv section on the line33 of Fig. 2,"showing the working parts in position to receive a charge of material; i i

. Fig. 1 is a similar view showing the position of the parts just prior to the completion of the compression. stroke of the plunger; r

Fig. 5 is a similar view showing the position of the parts immediately prior to the discharge of the briquet;

. Fig. 6 is a detail perspectiveview of the plunger; 3 I M 1 Fig. 7 is a detail perspective view of the compressing cylinder. j The supporting frame 1 of the machine may be of any convenient orpreferred construction and while I have illustrated a sin? gle compressing mechanism, it is to be .understood that the construction permits dupllcatio-n of the operating mechanism so that the invention may be operated in gangs driven from a common shaft. In the illustrated embodiment of the invention, 'longi- 'shaft is. a pinion 5 meshing with a larger gear 6 which is secured upon the end of a crank shaft-7 j ournaled in suitable bearings 8 upon the rails 2. Between the gear 6 and the side of the frame or the adjacent rail 2, a tappet 9 is secured upon the crank shaft 7 and this tappet 9 is adapted to impinge upon a. trigger 10 which is carried by the upperarm 11 of an angle lever which is fulcrumed upon a pin 12 on the side of the rail 2, as clearly shown. The lower or depending arm of this angle lever is turned laterally, as shown at 18, so as to extend under the rail 2 and has its extremity turned downwardly in the median longitudinal. plane of the machine. The trigger 10 is plvoted between its ends within a notch or bifurcation in the arm 11 and the upper edge ofthe trigger is straight, while the lower edge thereof is curved at its ends, as clearly shown in Fig. 1. It will also be noted upon reference to Fig. .1 that the straight flat upperedge 14 of the trigger bears against the top plate 15 of the arm 11 sothat when the gearwheel 6 is rotated in thedirection indicated by the arrow in Fig. 1 the tappet 9will impinge against the outer end of the trigger and will thereby oscillate the angle lever to which the trigger is pivoted, but if the gear wheel should be rotated in the opposite direction the trigger 'will yield to the impact of the tappet and will not actuate theangle lever so that breakage of the parts will be avoided. A link 16 is pivoted to the lower end of the angle lever and extends longitudinally of the machine, as shown, the end of the link remote from the lever being pivoted to the lower end of an oscillatory bar 17 which is fulcrumed between brackets 18, depending from the frame, and has its upper end formed into a curved rack 19 which meshes with a rack 20 on the-"under side-of the coni'pi essinghcylin der 21.

The end of the frame remote from the driving shaft i is constructed to provide an abutment 22 and the inner opposedlfacesuo-fi the side rails in'nnediately adj acentthe inner face of isal'd abutment are recessed, asshown e The compressii'igcylinder 21' is open at both ends and is provided at 'diametricallyop'posite points with projections or lugs rest? ng upon and slidable on the bottoms ofrec'esses 31 Tormedinthe side rails 2,asiclearly showi in Fig. 1, while caps 32 are seci ired upon the side rails so as to extenchover the said recesses and thereby hold the said lugs upon the bases of the recesses 31; The cylinder is thus permitted to reciprocate longitudinall of the frame and is held against rotation about its ownaxisfand itis normally held at the forward; limit of its 'niovement-by springs 33'w hich are disposed at the sides of the machinearid areconnec'ted at "their opposite ends mam forward guide lugs 80 and "to stiita-ble brackets or-projeceons 34 on the sides or "theimac hine. The actidn of the 'segm'ental geai' 19-anc1 the rack QO'i's to retract" the cylinder in opposition to the s ring-s 38 as willbepresently"more any set-forth. Upon its upper-"si'de the -.com'- pressing cylinder carries a hopper 35 through which the material-to be compressed is fed into the cylinder, in; advance-of the V plunger and the material maybe 'su'pplied to this hopper from an eoavenieac term-of coiwey'er or other feeding device ori'f the machine be set upfordomestic-use the niaterm-1 may befed 'manually to the-hopper.

The-plunger consists are foi ward m'ember 36 and: areas *ine'inber' 87' whichare of s'iich diameter as to fi't closely within the conipressing' cyl'indeig but capable of movement longitudinally within the cylinder The forward member 36 of the-plunger 'hasyits forward end' provided" iwitl'i a recess '38 Corresponding to "the recess-25 in-tl'ie jaw -24 and is also eonstnicted witlr a'n aiK-iahcavity 39 which-receives a reduced extension d0 from the front end "of the plunger mein'br-BF. A lbngitud-inal slot-el is formed through the extension 40 and a; pin 42 is carried by the fiirward member 36 mar xtends throu-gh the said s'lotso as-togiiide therear'member 37an'd prevent relative rotary movement between the pliingermembers. A spring-43is coiled around the extension 40 between the member 37 and-the member 36 and thls springshould be ofsuflioient-strength to hold the members normally in extended relation, it being des'ifg'ine'dto yield only when a large rock or other hard foreign substance happens to be within: the material fed into the compressing cylinder. Tl 1 e rear end of the rear plunger nie'inber 37"is pivdtally connected to a pitman 4A which has its rear end mounted. upon thecrank of the shaft 7 as sh w, and as wi'l'l' be readily understood. The plunger member ihay be pivoted directlyto the' end or the pitman as will be readily understood, but inorde'r to provide forajvariatidn in the size of the bflefn'etf without disassembling" the parts of theniachine, I employ the-"connection illustrated 1n the accompany1ngd1TiLW- ings in which the plunger member is==con-' iiig an eye li atfits'rear endi toieceive the pivot pin or pin-t le 'ISinSerted' through the said eye and the e'jnd oithepitman, as-shown.

When the plunger and cylinder start to move rearwardly,-the tension upon the spring wlll, of course,be released .and the ejector will then be moved rear- .wardlyslightly but sufficiently to loosen the The rotation of the crank shaft will, of course, carry the tappet 9 past the trigger 1%, whereupon the springs 33 will at once contract and pull the cylinder to its forward position ready to receive a fresh charge of material, but the plunger will continue to retract until its front end is in the same plane as the rear edge of the exit from the hopper 35 or in rear of said plane to permit the material fed into the hopper to pass directly into the cylinder. A second compression stroke will then be effected and the operation repeated indefinitely.
